spines ; those of the lateral line are much elevated, twice or thrice 

 the size of the others. A short, elliptical, pearl- coloured patch on 

 the back of the tail, close to the root of the caudal fin ; lower parts 

 with the pearl-coloured dots usually found in this genus. 



Pacific Ocean. 

 a. Four and a half inches long. Collected by Dr. Robertson in 

 lat. 43° 30' S. and long. 123° E. 



This is perhaps the same species as that found by Bennett, and 

 described as Scopelus stellatus (Whaling Voy. ii. p. 288). However, I 

 infer this more from the identity of the locality where these fishes have 

 been found, than from the very defective description and rude figure. 



b. Eye large ; a horizontal spine above the orbit. 

 14. Scopelus maderensis.

The height of the body is nearly one-fifth of the total length 

 (without caudal), the length of the head nearly one-third ; the 

 least depth of the tail is one-half of the height of the body ; the 

 depth of the head contained once and two-thirds in its length ; 

 eye large, but a little less than one-third of the length of the head, 

 and more than the width of the interorbital space. A horizontal 

 spine projects forward from each superciliary edge. The distance 

 between the posterior margin of the orbit and the praeopercular edge 

 is one-half of the diameter of the eye, the posterior margin of the 

 praeoperculum being oblique. Snout obtusely conical, not very short, 

 more than half as long as the orbit. Cleft of the mouth oblique, 

 with the lower jaw received within the upper. The maxillary 

 reaches to the angle of the prseoperculum, and is gradually and 

 slightly dilated behind. The origin of the dorsal fin is midway be- 

 tween the extremity of the snout and the root of the caudal fin, above 

 the base of the inner ventral rays ; its last ray is in the vertical 

 from the origin of the anal fin. A series of three or four small spines 

 bent backwards, above and below, before the root of the caudal. 

 Pectoral fin very long, extending to, or nearly to, the vent. Scales 

 smooth, very thin , deciduous, those of the lateral line being the largest. 



This species has the pearl- coloured dots on the lower parts as 

 usual in this genus, but there is no glandular apparatus on the back 

 of the tail, and only a very small round patch near the nostril.
